Identifier: http://hdl.handle.net/1959.14/199607
Description: The compact radio source Sgr A* is coincident with a 4 × 10⁶ M⊙ black hole at the dynamical center of the Galaxy and is surrounded by dense orbiting ionized and molecular gas. We present high-resoluti ... More

Identifier: http://hdl.handle.net/1959.14/178705
Description: The X-ray and near-IR emission from Sgr A* is dominated by flaring, while a quiescent component dominates the emission at radio and submillimeter (sub-mm) wavelengths. The spectral energy distribution ... More

Identifier: http://hdl.handle.net/1959.14/130147
Description: We have investigated the nature of flare emission from Sgr A* during multi-wavelength observations of this source that took place in 2004, 2005, and 2006. We present evidence for dimming of submillime ... More

Identifier: http://hdl.handle.net/1959.14/75100
Description: Sgr A*, the massive black hole at the center of the Galaxy, varies in radio through X-ray emission on hourly timescales. The flare activity is thought to arise from the innermost region of an accretio ... More

Identifier: http://hdl.handle.net/1959.14/9896
Description: Although Sgr A* is known to be variable in radio, millimeter, near-IR, and X-rays, the correlation of the variability across its spectrum has not been fully studied. Here we describe highlights of the ... More
